摘要： An entire radio transceiver can be completely integrated into one IC chip. In order to integrate the IF filters on the chip, a heterodyne architecture with a low IF is used. A single, directly modulated VCO is used for both up-conversion during transmission, and down-conversion during reception. Bond-wires are used as resonators in the oscillator tank for the VCO. A TDD scheme is used in the air interface to eliminate cross-talk or leakage. A Gaussian-shaped binary FSK modulation scheme is used to provide a number of other implementation advantages.

摘要： Methods and apparatus are disclosed for reducing mobile terminal energy consumption during data transmissions by allocating resources and adapting link parameters in an energy-aware manner, based on throughput requirements and prevailing signal propagation conditions. A combination of transmit parameters designed to minimize the total energy consumed during data transmission is selected based on a throughput requirement and a path loss associated with a data transmission by a mobile terminal. The combination of transmit parameters includes a bandwidth allocation and may also include a modulation format, coding scheme, and transmit power setting, as well as parameters relating to multiple-antenna transmit schemes. The bandwidth allocation may correspond to a number of sub-carriers of an OFDM signal, or may correspond to a number of resource blocks in an SC-FDMA signal.

摘要： A method of calibrating a first clock signal using a second clock signal and a plurality of calibration periods may include generating incremented counter values at a counter responsive to edges of the second clock signal. For at least two of the plurality of calibration periods, an initial incremented counter value from the counter may be stored in memory at an initial edge of the first clock signal for the respective calibration period, a final incremented counter value may be stored in memory at a final edge of the clock signal for the respective calibration period, and the at least two of the plurality of calibration periods may be overlapping with different initial and final edges of the first clock signal. For each of the plurality of calibration periods, a number of edges of the second clock signal occurring during the respective calibration period may be determined using the initial and final incremented counter values stored in memory. A relationship between the first and second clock signals may be determined using a sum of a number of edges of the second clock signal occurring during each of the plurality of calibration periods and using a sum of a number of first clock signal cycles occurring during each of the plurality of calibration periods.

摘要： An apparatus in a wideband radio transceiver for mitigating interference between a wideband radio operating in a wide frequency band and a narrowband radio operating in a narrow frequency band within the wide frequency band. The effects of transmissions by the wideband radio on the narrowband radio are reduced by creating by the wideband radio, a transmitter notch of decreased transmit power centered at a frequency in the wide frequency band that is fixed in relation to the wideband carrier frequency. The wideband carrier frequency is then adjusted so that the transmitter notch is aligned with the second radio's narrow frequency band. The effects of transmissions by the narrowband radio on the wideband radio are reduced by creating by the wideband radio, a fixed receiver notch of decreased receiver gain in the wideband receiver, and aligning the narrowband signal with the fixed receiver notch.

摘要： Some embodiments of the present invention are directed to methods of operating communication terminals. A wireless communication link is established between first and second communication terminals and communication signals are exchanged therebetween. The first communication terminal is controlled to continue over time to increase a power level at which it transmits communication signals to the second communication terminal in response to detecting loss of the wireless communication link and while continuing attempts to reestablish the communication link with the second communication terminal. The first communication terminal is further controlled, in response to detecting loss of the communication link, to increase a level of attenuation that it applies to communication signals from the second communication terminal, and to then more gradually decrease the level of attenuation over time in response to continuing attempts to reestablish the communication link with the second communication terminal.

摘要： Method and device for interference cancellation. A radio access unit comprises a plurality of directionally separated antenna elements (41k, K=1, 2, . . . , L) for receiving signals transmitted by a plurality of remote units. From signals received by each of the antenna elements (41k) first weighing factors (g(1)k) are determined (49), for optimally selecting signal of a first remote unit (521). A first radio signal (s1) of the first communication unit (521) is provided by weighing (44) the received signals using the first weighing factors (g(1)k). For a further radio communication unit (52i) further weighing factors (g(i)k) are determined. A corrected further radio signal (s′i) is provided each time by subtracting (46) from the further radio signal (si), previously obtained corrected radio signal (S′i-1, S′i-1, . . . ) weighed by the further weighing factors (g(i)k), till a stop criterium has been satisfied.
